Background To determine the diagnostic accuracy of preoperative T/N stage using MRI in lower and middle rectal cancer patients and the impacts on clinical decision-making. Patients and methods There were 354 patients recruited from May 2017 to February 2019. MRI was performed within 2 weeks before surgery. Histopathologic results were evaluated for the postoperative T/N stage and MRI diagnostic accuracy was assessed based on the postoperative histopathologic results. Accuracy, sensitivity, specificity, positive predictive value, negative predictive value, and Kappa values were used to evaluate MRI diagnostic accuracy and analysis consistency compared with postoperative histopathologic staging. Results Overall MRI diagnostic accuracy was 78.2% and 56.8% for T1-4 and N0-2 staging. The Kappa values were 0.625 and 0.323 for T1-4 and N0-2 staging, respectively. After combination, MRI diagnostic accuracy was 85% and 69.5% for T and N staging. The Kappa values were 0.693 and 0.4 for T and N staging. The diagnostic accuracy of MRI for treatment decision-making was 79.1%. Conclusion MRI enables a highly accurate preoperative assessment of T stage but only a fairly accurate preoperative assessment of the N stage for rectal cancer with surgery. The diagnostic accuracy of MRI for treatment decision-making is promising.Objective Depression and attention-deficit hyperactivity disorder (ADHD) are prevalent and highly comorbid. ADHD symptoms are associated with specific dependent (i.e., self-generated) stressors in children, and there is a strong link between dependent stress and depression. Despite continued comorbidity of ADHD and depressive symptoms into adulthood, it is unknown whether stress generation mediates the relation between ADHD and subsequent depressive symptoms in emerging adulthood, a period of heightened stress. Method We tested this mediation model in a semester-long longitudinal study of 224 college students (aged 18-23 years). We additionally tested whether this model differed between inattentive versus hyperactive/impulsive ADHD symptoms given evidence that they vary in their relations to stress and depression. Results Dependent stress mediated the association between total ADHD symptoms at baseline and later depressive symptoms; these effects were equivalent for inattentive versus hyperactive/impulsive ADHD symptoms. Conclusion These findings suggest stress generation as a mechanism for increased depression in individuals with ADHD symptoms.Objective In this case-control study, we retrospectively analyzed the intestinal flora compositions of patients with early-stage chronic kidney disease (CKD). Methods Forty-seven patients with early CKD who were treated at the Traditional Chinese Medicine Hospital between March and October 2018 were enrolled, and 150 healthy volunteers were enrolled in the healthy control group. Fresh stool samples were collected. The V3-V4 region of the bacterial 16S rRNA was amplified via PCR. https://www.selleckchem.com/products/acetylcysteine.html Biterminal sequencing was performed using the Illumina MiSeq platform. The flora compositions were compared between the two groups. Results The Chao1 and Shannon indices showed significantly lower intestinal flora diversity and abundances in the CKD group than in the healthy controls. Beta diversity analysis revealed notable differences in the intestinal flora compositions between the groups. At the phylum level, Actinobacteria and Proteobacteria abundances were significantly higher in the CKD group. Thirty-one species differed significantly between both groups, among which, differences in Ruminococcus and Roseburia displayed the highest diagnostic values for distinguishing CKD patients from healthy controls. Conclusions Intestinal flora compositions are altered in early-stage CKD patients among the Han population in southwestern China.Objectives The transition to motherhood is associated with declines in physical activity in women. Working mothers may be particularly at-risk for low levels of physical activity, since they have to balance the competing interests of work and family life, and exercise often takes a backseat to more seemingly pressing concerns. The potential benefits working mothers can experience from physical activity are numerous. The objectives of this study were to evaluate the percentage of working mothers from the United States who met the World Health Organization's and the American College of Sports Medicine's recommended guidelines for weekly physical activity and investigate the associations between physical activity, quality of life, and self-rated work productivity in this sample of working mothers. Methods Participants were 334 working mothers from the United States (mean age = 35.00 years; standard deviation (SD) = 5.85; 77.8% White) recruited from a Qualtrics research panel. To be eligible to participate in thequality of life (r = 0.39; p less then 0.001) and self-rated work productivity (r = 0.13; p less then 0.05). Only the association between physical activity and quality of life remained significant in a multivariate analysis (standardized beta coefficient = 0.33; p less then 0.001) after controlling for race/ethnicity, maternal singular annual income, and maternal highest level of education. Conclusion Our findings highlight that working mothers in the United States are a group at risk for low levels of physical activity. Given the great benefits that these women do experience as a function of getting exercise, it is critically important we pay more attention to how individual, organizational, and societal-level interventions might assist them in attaining target levels of physical activity.Objectives This study investigated the level of acceptance in Singapore of the eight principles of design underpinning the Environmental Assessment Tool-High Care (EAT-HC), which is commonly used in Australia to evaluate environments for the care of people living with dementia. A secondary goal was to identify topics particularly relevant to the Singaporean context, which are not included in the Australian EAT-HC. Background This study was undertaken in preparation for the development of a Singaporean version of the Australian EAT-HC. Methods Discussions from 23 focus groups involving 150 family caregivers, aged care staff, administrators, and architects were recorded and thematically analyzed to identify the characteristics of the principles underpinning the EAT-HC that are unlikely to be relevant in a Singaporean version and to identify additional topics required to tailor it to reflect the Singaporean culture. The thematic analysis was supplemented with quantitative data obtained through the use of simple Likert-type scales measuring the appropriateness of each principle in the Singaporean context.
